Private Venetian Island with Vineyards, Chapel and Helipad Lists for $28.3M

A rare private-island offering in the Venetian Lagoon

The market for real estate in Italy sometimes produces properties that read like a novelist’s set piece. This is one of those moments: Isola Santa Cristina, a 72-acre (about 29-hectare) private island in the Venetian Lagoon, is on the market for $28.3 million, offered by Venice Sotheby’s International Realty. For buyers and investors tracking luxury property Italy, this is not a typical villa listing; it is a self-contained estate with agricultural production, marine infrastructure and an ownership history tied to the Swarovski family.

In this report we walk through what is on offer, what a purchase like this means in practical terms, the environmental and regulatory constraints you will face, and the likely buyers for a property of this type. Our analysis is based on the listing details and statements from the trustee and listing agent accompanying the sale.

What exactly is for sale: buildings, acreage and amenities

The core of the estate is a main residence with substantial domestic and operational infrastructure that supports private use and ongoing agricultural production.

• Total area: 72 acres (approximately 29 hectares)
• Listing price: $28.3 million
• Main villa: 9,250 sq ft (four floors) with 9 bedrooms and 9 bathrooms; interiors by Studio Architetto Mar; includes two reception rooms, a formal dining room, a chef’s kitchen, a grand veranda and an altana (roof terrace) with lagoon views
• Farmhouse: roughly 6,100 sq ft, with two bedrooms, two bathrooms, its own kitchen and a self-contained apartment
• Additional structures and facilities: a chapel, heated saltwater swimming pool, dock and boathouse, helipad, and storage/operational buildings
• Transport assets included: five boats (three for operations, two for leisure)
• Agriculture: about seven acres planted with Merlot, Chardonnay and Cabernet vines, plus apricot and plum orchards, vegetable gardens and beehives producing saltmarsh honey
• Water and power: water supplied from three deep wells; electricity from the mainland with a gasoline backup generator and supplemental solar capability
• Current investment: more than $2 million being invested in upgraded agricultural and technical infrastructure

This is being marketed as a comprehensive estate rather than a simple island plot. The combination of residential, agricultural and marine assets is uncommon on the market near Venice.

Ownership history and stewardship priorities

The island was purchased in 1986 by Gernot Langes-Swarovski, a descendant of the Swarovski crystal family, who bought it to create a private retreat within easy reach of the Swarovski headquarters in the Austrian Tyrol. Following his death in 2021, control of Isola Santa Cristina passed to a family trust, SEGNAL Privatstiftung. Dr. Christoph Volk, chair of trustees, has said the trustees want a new owner who will respect the island’s ecological values and ongoing stewardship.

The current owners have invested in maintaining and modernizing the property while retaining its agricultural focus. Fish-farming operations were redeveloped in partnership with Ca’ Foscari University in Venice, and the trustees have highlighted sustainability and the island’s role within the traditional fishing culture of the lagoon.

Anne-Marie Doyle, owner and managing director of Venice Sotheby’s International Realty, describes the estate as a retreat to "recharge, relax, and commune with nature, alone or with friends and family." That phrasing tells you who the marketer imagines as the buyer: a high-net-worth individual or family seeking privacy, amenity-rich living and a measure of productive land use.

Agricultural profile and ecological infrastructure

Isola Santa Cristina is presented as a working estate. This is not decorative landscaping; it is production that supports part of the island’s operating model.

• Vineyards: roughly seven acres planted with Merlot, Chardonnay and Cabernet. These plantings are not large-scale commercial acreage, but they are substantial for private production and can support boutique winemaking or hospitality-focused activities.
• Orchards and vegetables: apricot and plum orchards plus vegetable gardens support a degree of self-sufficiency and seasonal production for on-island consumption or small-scale retail.
• Aquaculture: the island operates a fish-farming operation that was modernized with academic collaboration, indicating regulatory compliance and an active production program.
• Beekeeping: beehives produce a distinctive saltmarsh honey tied to the lagoon’s environment.

The owners are currently investing more than $2 million in agricultural and technical upgrades. For buyers interested in agritourism, private-label wine or small-scale food production, the infrastructure and the cooperation with local university researchers provide a head start. But if your aim is to scale production into a commercial agribusiness, know that the island’s size, lagoon ecology and regional regulations will shape what is permitted.

Access, logistics and operational realities

Owning a private island near Venice is romantic, but it is also logistically complex. We list the practical considerations you will face if you become the new owner.

• Transport and access: the island includes a helipad and five boats. Routine passenger and goods movements rely on boats, and emergency access or VIP arrival can use the helipad—though aviation operations require local approvals and ongoing compliance with Italian aviation norms.
• Energy and utilities: electricity is supplied from the mainland with a gasoline generator for backup and some solar capacity. Expect to manage fuel logistics, generator maintenance and, if you increase power demand, further solar or battery investments.
• Water: three deep wells supply water for domestic and agricultural use. Buyers should plan for well testing, maintenance and possible contingency supplies for prolonged dry periods or drought management measures required by regional authorities.
• Staffing: a property of this size and complexity requires staff for maintenance, agriculture, security, boating and housekeeping. Housing for staff is present in the farmhouse and other service buildings, but recruitment and retention on an island have different cost and logistics profiles than mainland properties.
• Security and insurance: insuring a private island with agricultural operations, boats and a helipad is specialized and usually more expensive than for a detached villa. You will need insurers willing to underwrite maritime assets, structural risks from salt air and flood exposure in a lagoon environment.

These factors mean that running costs are likely a significant percentage of purchase price on an ongoing annual basis. We recommend commissioning technical, marine and agricultural surveys as part of due diligence.

Legal and regulatory considerations for buyers of island property in Italy

Buying property Italy is a cross-section of national law, regional planning, and local environmental regulation; buying an island in a UNESCO-protected lagoon increases complexity.

Key issues to cover in due diligence:

• Zoning and planning restrictions: the Venetian Lagoon is protected and parts of it are subject to strict land-use controls. Any renovations, expansions or new constructions will require permits from regional and municipal authorities, and could involve special procedures tied to heritage or environmental protection.
• Environmental and marine regulations: aquaculture and fishing rights, water use from wells, discharge approvals and habitat protection rules may apply. The fact that fish-farming work was carried out with Ca’ Foscari University suggests the current operations are compliant, but any changes may need fresh approvals.
• Heritage and UNESCO considerations: the lagoon is a UNESCO World Heritage Site, and that status can influence development approvals, conservation obligations and even insurance conditions. You should ask your legal team to confirm whether structures are protected or if the wider setting imposes limitations.
• Aviation permissions: the helipad is an asset but its use is regulated by aviation authorities.
